really does depend which bar - for some such as 'Chervillo' it is as 'designer and bling' as you dare plus 18 year old arm candy PLUS 18 stone bodyguard...for others like Murphy's the 'pauncy ex-pat rugby shirt, jeans and trainers' look is what you should go for
There are yet other bars where the girls wear nothing but fuit salad and the guys wear silly grins on thier faces - but I dont go in those ;-)
